Cho đến bây giờ tôi đã sử dụng các dịch vụ Web và nó hoạt động tốt. Tôi đã thêm một dịch vụ WCF mới.
Tôi đang gọi các dịch vụ bằng jQuery. Đây là cách tôi sử dụng jQuery để tiêu thụ các dịch vụ Web:Tiêu thụ dịch vụ WCF bằng cách sử dụng jQuery
$.ajax({
dataType: 'json',
processData: false,
type: 'POST',
contentType: "application/json",
url: url,
context: s.context,
data: JSON.stringify(s.data),
error: function (xhr, textStatus, errorThrown) {
if (s.error != null) {
s.error(xhr, textStatus, errorThrown);
}
if (s.error_addition != null) {
s.error_addition(xhr, textStatus, errorThrown);
}
},
success: function (data, textStatus, xhr) {
s.success(data.d, textStatus, xhr);
subscriber.setDone(data.d);
}
});
Tôi không thể sử dụng phương pháp này để tiêu thụ dịch vụ WCF. Đây là cách dịch vụ WCF được xác định:
[ServiceContract]
public interface ISystemService
{
[OperationContract]
[WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped, ResponseFormat = WebMessageFormat.Json)]
Reason[] GetCallReasons();
}
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class SystemService : SimTaskService, ISystemService
{
public Reason[] GetCallReasons()
{
//...
}
}
Tôi không thêm gì vào cấu hình web cho dịch vụ WCF.
Sử dụng cáy, đây là tiêu đề phản ứng:
HTTP/1.1 415 Cannot process the message because the content type 'application/x-www-form-urlencoded' was not the expected type 'text/xml; charset=utf-8'.
Dưới đây là web.config của tôi:

Có ai biết làm thế nào để sửa chữa nó?
Câu hỏi đặt ra là tại sao bạn có được hình thức bài thay vì bài đăng json với kiểu nội dung 'application/json'. Ngoài ra tại sao bạn đăng dữ liệu khi hoạt động của bạn không mong đợi bất kỳ thông số đầu vào nào? –
@Ladislav Mrnka: Đây là một phương pháp chung. dữ liệu thực sự là đối tượng trống. "Json post" là gì? – Naor
@Naro: Mã bưu điện của web.config –
